Synopsis

The remote Mac OS X host contains a web browser that is potentially affected by an integer overflow vulnerability.

Description

The installed version of Firefox 3.6.x is earlier than 3.6.27 and is, therefore, potentially affected by an integer overflow vulnerability in libpng, a library used by this application.
